Detailed Description

NTK 24592 is a direct-fit oxygen sensor from the Direct Fit Oxygen Sensor line, built for upstream applications where accurate air/fuel ratio feedback is required. As part of NTK's oxygen sensor program, it reflects the brand's focus on OE-style fit, form, and function, with manufacturing controls that support consistent sensor performance. This part number, 24592, is listed for Hyundai Accent, Hyundai Elantra, and Hyundai Tiburon applications with upstream placement.

The sensor uses a heated design, a threaded mount, and a 4-wire layout to match the original-style configuration. For Hyundai Accent, Hyundai Elantra, and Hyundai Tiburon service, NTK 24592 provides a fitment-specific replacement option for upstream oxygen sensor repair.

What It Is Used For

• Replacing a failed upstream oxygen sensor
• Restoring air/fuel ratio feedback to the engine control system
• Addressing sensor-related fault codes and drivability concerns
• Correcting slow sensor response or inaccurate exhaust readings

Installation Notes and Tips

Verify the upstream position and match the threaded, heated 4-wire configuration before installation. Confirm the harness length and thread diameter against the original sensor, and use the vehicle's application data to ensure the correct fit for the Hyundai Accent, Hyundai Elantra, or Hyundai Tiburon. The notes for some applications specify Bank 1 Sensor 1 and a production-date restriction on the 1997 Hyundai Accent.

Quality Assurance

NTK states that its oxygen sensors are extensively tested during manufacturing to meet or exceed OE specifications. The brand also identifies itself as a major original equipment oxygen sensor supplier, with OE application technology support across its product line. Part number 24592 is backed by that OE-focused manufacturing approach.
